PURPOSE: To evaluate the diagnostic value of gross bloody stools as a predictor of intussusception. METHODS: We reviewed 159 cases retrospectively that had an ultrasound examination for diagnosis of intussusception from January 2001 to December 2003 at Ilsin Christian Hospital. We compared each symptom and assessed the diagnostic value of gross bloody stools in the patients with suspected intussusception. RESULTS: Thirty-six of the 159 patients had intussusception. Of 36 patients with intussusception, 19 (52.8%) children were male and 28(77.8%) children were younger than two years. The most common symptom was intermittent abdominal pain or irritability. But its frequency among the intussusception (24.2%) was lower than frequency of gross bloody stools(50.9%). The sensitivity, specificity, positive predictive value(PPV) and negative predictive value(NPV) of gross bloody stools in patients with suspected intussusception were as follows; sensitivity=77.8%(95% CI 60.8-89.9), specificity=78.0%(95% CI 69.7-85.0), PPV=50.9%(95% CI 37.1-64.6), NPV=92.3%(95% CI 85.4-96.6)(Diagnostic accuracy 78.0 %; 95% CI 70.7-84.2). CONCLUSION: It is useful for diagnosis of intussusception to confirm the presence of gross blood in stools.

PURPOSE: Foreign body aspiration in the tracheobronchial tree is a common medical emergency in children and represents an important cause of morbidity and mortality. This study was aimed to analyze the clinical spectrum of tracheobronchial foreign bodies in children and to evaluate the causes of late diagnoses. METHODS: A total of 108 patients with foreign body aspiration were recruited in the last 10 years, who had a flexible or rigid bronchoscopic examination. The age, sex, symptoms, causes of aspiration, radiologic findings, and clinical courses were investigated retrospectively. Patients were divided into 2 groups according to the elapsed time from aspiration to a definite diagnosis as early (< or =24 hours after aspiration) and late diagnoses (>24 hours after aspiration). The two groups were compared for clinical courses, radiologic findings, and the duration of admission of early- and late-diagnosed foreign body aspiration. RESULTS: Approximately 80% of the patients were less than 24 months of age and the most common symptoms were the sudden onset of a cough. Hyperinflation or obstructive emphysema (52.8%) and normal chest radiographs (19.4%) were the most frequent radiologic findings. Plain chest radiographies revealed visible foreign bodies in 7.4% of all patients with foreign body aspiration. Nuts were the most common foreign bodies aspirated. Sudden onset of a persistent cough and fever were predominant in the late-diagnosed group.(P<0.05) CONCLUSION: Our results suggest that clinical suspicion upon interviewing is enough to indicate bronchoscopy. The best way to reduce the number of accidents and deaths associated with foreign body aspiration is to promote public prevention polices.

This study was conducted to examine the effect of chronic low dose organic solvent exposures in the industries towards then neurobehavioral functions of workers subjective symptoms on neurobehavioral function as well as a visual reaction time test (Flicker test) were administered to 94 exposed and 162 unexposed workers in a oil refinery and some other auto-repair shops. The results obtained were as follows: 1. Symptom complaints were higher and Flicker test values were lower in exposed workers than in unexposed workers. 2. Flicker values were inversely correlated with urinary Hippuric acid concentration in exposed workers (r=-0.26, p<0.05). 3. Flicker values were inversely correlated with subjective symptom score (r=-0.15, p<0.05). Low Flicker value were also related with some subjective symptoms such as "Dimmed vision", "Nightmare", "weakness on extremity" in workers as a whole. While symptoms of "Dimmed vision", "Nightmare" only observed among exposed workers.

OBJECTIVES: The objective of this study was to examine the relations between total vegetable and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults. METHODS: This study used dietary intake and health data of 6668 subjects aged 20 years and over from the 2010–2011 Korea National Health and Nutrition Examination Survey (KNHANES). Daily intakes of total vegetables and Kimchi were assessed by 24-hour recall data. The odds ratio of Mets risk according to daily intake of vegetables and Kimchi was analyzed, respectively. RESULTS: The highest consumption of total vegetables was associated with a lower risk of abdominal obesity (multivariable adjusted OR=0.56, 95% CI: 0.33, 0.93) in men and lower risk of Mets (multivariable adjusted OR=0.67, 95% CI: 0.47, 0.94) in women. Kimchi consumption was not related to the risk of Mets in both men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure (Q1 vs Q5, multivariable adjusted OR=1.34, 95% CI: 0.95, 1.90, P for trend= 0.0261) in women. CONCLUSIONS: A higher intake of vegetables was associated with decreased risk of abdominal obesity and Mets in both men and women, respectively. A higher consumption of Kimchi was not related to the risk of Mets in both in men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure in women.

OBJECTIVE: To evaluate the therapeutic effect of botulinum toxin A (BTX-A) injection on spastic gastrocnemius (GCM) and tibialis posterior muscles (TPo) by using the foot pressure measurement system (FPMS). METHODS: Eighteen ambulatory CP patients were recruited in this study. BTX-A was injected into the GCM at a dose of 6-12 units/kg and TPo at a dose of 4-9 units/kg according to the severity of equinus and varus deformity. Foot contact pattern, pressure time integral (PTI), coronal index using the FPMS and Modified Ashworth Scale (MAS), and visual inspection of gait pattern were used for evaluation of the therapeutic effect of BTX-A injection. Clinical and FPMS data were statistically analyzed according to the muscle group. RESULTS: A significant decrease in the MAS score of the GCM and TPo was observed, and spastic equinovarus pattern during gait showed improvement after injection. The GCM+TPo injection group showed a significant decrease in forefoot, lateral forefoot pad, and lateral column PTI, and a significant increase in hindfoot PTI and coronal index. In the GCM only injection group, forefoot PTI and lateral column PTI were significantly decreased and hindfoot PTI was significantly increased. The TPo only injection group showed a significant decrease in lateral column PTI and a significant increase in the coronal index. Change in PTI in the hindfoot showed a significant correlation with the change in MAS score of the GCM. Change in PTI of the lateral column and coronal index showed a significant correlation with the change in MAS score of the TPo. CONCLUSION: The FPMS demonstrated the quantitative therapeutic effect of BTX-A on abnormal pressure distribution in equinovarus foot in detail. The FPMS can be a useful additional tool for evaluation of the effect of BTX-A injection.

This investigation was designed to analyze the degree of dental compensation according to horizontal components of craniofacial skeleton and to investigate correlation between dental compensation and craniofacial pattern in skeletal class III malocclusion. The material selected for this study consisted of standard lateral cephalogram of 59 subjects in normal occlusion group, 91 subjects in mild skeletal class III malocclusion group and 58 subjects in severe skeletal class III malocclusion group. The mild skeletal class III malocclusion group was divided into two groups, one was class III malocclusion without anterior crossbite group and the other was class III malocclusion with anterior crossbite group. The data were analyzed by Quick-ceph image program. The results were as follows. 1. Mild skeletal class III malocclusion without anterior crossbite group showed the most labial inclination of upper incisors, followed by severe skeletal class III malocclusion group and mild skeletal class III malocclusion with anterior crossbite group, the Latter showing the least. The amount of lingual inclination of lower incisors was the largest in severe skeletal class III malocclusion group, and there was no statistically significant difference between mild skeletal claw III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior crossbite group. 2. There were little differences in vertical skeletal structure between mild skeletal class III malocclusion without anterior crossbite group and mild skeletal class III malocclusion with anterior cwssbite group, they showed statistically significant differences in the upper incisors measurements. 3. The measurements of lower incisors in mild skeletal class III malocclusion without anterior crossbite group and upper incisors in mild skeletal class III malocclusion with anterior crossbite group represented a high correlation with skeletal structure. Especially, deltaIMPA and deltaFMIA of lower incisor measurements, and deltaU1-FR deltaUi-SN of upper incisor measurements showed high correlation with skeletal structure in each group. 4. deltaIMPA and deltaFMIA of lower incisor measurements showed high correlation with skeletal structure in all groups. deltaUI-FH, deltaU1-SN and Ui-facial plane(mm) of upper incisor measurements represented higher correlation with skeletal structure than any other upper incisor measurements.

PURPOSE: We evaluated the prognostic factors of open globe injuries in children and adolescents, and compared the ocular trauma score (OTS) and pediatric penetrating ocular trauma score (POTS). METHODS: We performed a retrospective review of 77 children under 18 years of age who visited our clinic with open globe injuries between May 1993 and April 2014. We investigated the factors that may affect final visual acuity. We also compared the OTS and POTS using receiver operating characteristic curves as a method to predict final visual acuity. RESULTS: By univariate analysis, an initial visual acuity less than 20/200, globe rupture, wound size greater than 7.0 mm, retinal detachment, lens dislocation, and total number of operations contributed to worse visual outcomes (<20/200). Conversely, central corneal involvement, traumatic cataract, wound size less than 7.0 mm, and initial visual acuity greater than 20/200 were better prognostic indicators (≥20/32). Both OTS and POTS had diagnostic value as a predictor of final visual acuity, although there were no statistically significant differences between the two scoring systems. CONCLUSIONS: Initial visual acuity and wound size are important prognostic factors for the final visual acuity in children and adolescent, following open globe injuries. Both OTS and POTS are reliable prognostic models for open globe injuries in children and adolescents.

Gastric metastasis from invasive lobular breast carcinoma is rare. Mostly gastrointestinal metastasis presents as one among multiple metastases, several years after primary diagnosis of breast carcinoma. Herein, we report a synchronously diagnosed gastric metastasis from invasive lobular carcinoma, mimicking primary gastric linitis plastica with pyloric obstruction. We reviewed clinical and pathological findings of gastric carcinoma metastatic from the breast. In particular, we focused on immunohistochemical studies of selected antibodies, including those for estrogen receptors, gross cystic disease fluid protein-15, and caudal-type homeobox transcription factor 2, for accurate differential diagnosis. Clinical suspicion, repeat endoscopic biopsy, and detailed histological analysis including immunohistochemistry are necessary for diagnosis of gastric carcinoma metastatic from the breast.

The purpose of this study was to investigate the relationship among eating habits, eating behaviors, obesity indices and serum leptin levels of 97 school children in the Daegu and Kyungpuk areas. The subjects consisted of 42 boys and 55 girls from the 4th and 5th grades. The prevalence rate of obesity was 63.6% in the males and 36.4% in the females. The nutritional status of the subjects was assessed using 24-hour dietary recalls and blood analyses. The mean serum leptin levels of the obese group (12.84 +/- 6.97 ng/ml) were significantly higher than those of the non-obese group (2.43 +/- 1.53 ng/ml)(p < 0.001). The mean eating behavior scores and MAR were significantly different in the two groups. Nutrient intakes were low and fell short of the RDA. Serum leptin levels showed a significant negative correlation with eating habit (r = -0.24) and eating behavior scores (r = -0.40)(p < 0.05, p < 0.001). It was speculated that nutritional intervention and education about the appropriate nutrient intake requirements of developing children might be necessary.

BACKGROUNDS/AIMS: The aim of this study is to clarify the safety and feasibility of laparoscopic hepatectomy, through comparing the early and late periods of perioperative outcomes. METHODS: We retrospectively analyzed 138 patients who underwent laparoscopic hepatectomy from January 2003 to June 2011, at Yeungnam University Hospital. We divided the total patients to early period (from January 2003 to February 2007, n=49) and late period (from March 2007 to June 2011, n=89) groups and compared the perioperative outcomes including the mean operation time, intra-operative blood loss, postoperative hospital stay, intensive care unit (ICU) stay, and duration of liver function test (LFT) normalization. RESULTS: The mean operation time was 308 minutes (range: 140-510) in the early group and 193 minutes (range: 40-350) in the late period group (p<0.001). The mean intraoperative blood loss was 171 ml (range: 50-1,200) in the early and 44 ml (range: 0-400) in the late group (p=0.005). The postoperative hospital stay was 9.7 days (range: 4-31) in the early and 6.8 days (range: 2-9) in the late period (p<0.001). The ICU stay hour was 21.6 hours (range: 0-120) in the early and 2.8 hour (range: 0-24) in the late period (p<0.001). The duration of LFT normalization was 5.7 days (range: 0-39) in the early and 2.1 days (range: 0-20) in the late period (p=0.003). The perioperative outcomes in the late period were better than the early period, which showed a statistically significant difference. CONCLUSIONS: Laparoscopic hepatectomy is feasible and can be safely performed in selected patients but requires a long experience in open liver resection and mastery of laparoscopic surgical skills.
